Tool command language.

Tcl (Tool Command Language) is a very powerful but easy to learn
dynamic programming language, suitable for a very wide range of uses,
including web and desktop applications, networking, administration,

mature yet evolving language that is truly cross platform, easily
deployed and highly extensible.
